13 Protons because the atomic number is the number of electrons and protons.
The atomic mass is protons plus neutrons because electrons are too small to measure.

What is the temperature difference if 300 cal are used to warm water

PIT_PIT [208]

Answer:

The temperature difference is $\frac{300}{m} Kkg^{-1}$

Explanation:

The formula that is to used is :

Δ $Q=ms$ Δ $T$

where ,

Δ $Q$ is the heat supplied in calories = 300cal
$m$ is the mass of water taken = m (assumed)
Δ $T$ is the change in temperature
$s$ is the specific heat of water = $1calK^{-1}Kg^{-1}$

ΔT :

$\frac{300}{m*1} \\=\frac{300}{m} Kkg^{-1}$
